Having reference to the illustrative embodiment which is shown in Figs. 1 to 5,

In this embodiment the feeler-tip 1 is mounted upon the rear portion of a carrier 2 that is movable forwardly and rearwardly in a loom, as heretofore. The feeling end 1 of the feeler-tip is directed rearward. The usual openings 6 and 7 are provided in the shuttle-box front-plate and the front Wall of the shuttle-body. respectively, to permit the said feeling end to enter the shuttle from the front side of the latter as the lay heats up, for the purpose of making contact with the said supply. The carrier 2,

as usual, is actuated by a spring (1)) w'i ,ch holds .it normally in its rearmost position but yields to permit the carrier to he pushed forward by the pressure of {he \veli.coutents of the shuttle against the fccli i cud of the feeler-tip as thc lay approaches iircut center, and moves the arrier uard to the normal poftrou thercoi a as ihc lay recedes. .DQl l l OEQHi availah constructions, and arrange a of carriers and actuating springs. means of supporting pacity for the erpur il nmwnusuis, .irc known in the a and in wine (Iiiiifi may be substituted for those heroin vshown. in this instance, the carricr is in (hr form of a slidebar, and occupies a. guide-way in an upstanding portion 10 of a stand 10". hciug held down within such gjuhlcutcv' by means of a crossbar 10". and has a rorl-lihc oi;- teusion 2 that pa forward through a hole in a second upstanding porti-iiu. 1U". oi the stand 10", and ihc aciuating pring is a coil-spring 9 that mounted upon the said extension 2 and cc-ulimul hotvvcen upstamli.

The normal position of the slide-bar. givmi to the same by the action oi spring J in tending to expand, is determined through contact of lateral projections 2, 2, thereof with the front of upstanding pm'tiou 10 of the stand 10. The supporting mains For the carrier-stand 10 may vary in practice. llcrein the carrier-shoal is supportml upon an outward extension 11 from a 'lccler-sfand 11, which latter is bolted to a .u'acliet lit projecting (juitvvar l from loouriraim '13 at one end of the oreas 0am. Th4 \'.1\l!'l(".l'- stand 10 is held in position upon excnsiou 11 of fecler-staud ll. by one or more bolts, and adjustable thereon in ihc direction from front to rear, or vice vcrsa. to provide for setting the icelur so that contact of the wefomass with the feclingnmul of the feelentip shall take placc at the proper point in the beatiugau movement oi the lay to secure the desired results ilu'ough the action of the parts. Fowler-s!and 11 is adjustable transversely of the loom along bracket 12 by means of bolls 11", 1].. and the slots 11", 11", in said bracket. in order that the feeling-end 1 of the icclcr-tip may be located so as to makc contact with the required portion of the length of ihc wettsupply and vv'c'l't-carricr in the shuttle.

During this deflection, the tension of spring 9 tends to keep carrier 2, and. consequently the point 1 of engagement of toe feeler-tip therewith, in the most rearward position. The efiect of this is that the feeler-tip first. tends to swing around pivot 1 as a fulcrum in the direction to draw rod a rearward. There by collar 6 becomes firmly engaged with the front face of lug (Z. in this manner the rearward position of rod a, and that of the pivot 6 connecting the tail of the feelertip with (4, becomes fixed, whereupon the pivot 3 becomes the effective fulcrum of the feeler-tip and during the remainder of its forward swinging movement the feelertip swings around such fulcrum and in doing so acts as a lever applying power at the pivot 1 to press the carrier 2 forward. The forward movement of the carrier thereby occasioned displaces it forward relative to rod (5. This relative displacement is utilized for the purpose of bringing about the desired change in the operation of the loom. In effect, the fcelertip has alternate fulcra, both of which are utilized duringthe indicating action, namely, a primary fulcrum 1 in connection with carrier 2, upon which it swings laterally toward and from its normal presentationposition, and a secondary fulcrum b in connection with the stop-device, upon which it swings in acting as a lever to move carrier 2 forward, and in being subsequently restored to presentationposition through the rearward movement of carrier 2 produced. by the action of spring 9 as the pressure against the feelenend 1 of the feeler-tip is relieved by the movement of the lay rearward.

The operation of the loom in which the feeler is employed is governed by the feelerparts that have been described, through supplemental. devices which are governed directly by the said feeler-parts. In general terms, so long as the said feeler-parts are driven forward by the push of the filling- ;mass with the feeler-tip in its normal position shown in Fig. 4, no change in the operation of the loom is occasioned, but when the forward movement takes place with the feeler-tip laterally-displaced as in Fig. 5 .by the. push of a substantially exhausted weftcarrier 4, so that the action just described takes place, the desired change in such operation is brought about. The said supplemental devices may vary in character and arrangement, and may include any suitable form of controller or transmitter. The drawings show a well-kuown form of con trollcr, operatively combined with the feelcr and governed thereby and itself controlling 'a catch 1S arranged for coac'tion with a striker. The striker is constituted in this instance by the weft-hammer 20 of the loom,

and the said catch is connected at its front end by a pivot 18 with an arm 19 belonging to the parts that are concerned the more immediately in bringing about the change in the operation of the loom.

The illustrated form of controller comprises a rockshaft ll that is mounted in bearings 11, 11, provided in connection with feeler-stand 11; an arm 15 fixed upon the outer end-portion of the said rockshaft and provided with an outwardly-projecting pin 15 for cooperation with the feelor-parts; and an arm 16 fixed upon the inner end portion of the said rocksliaft and carrying an inwardly-projccting pin 17 which enters a slot 18 in the catch 1.8". The height at which the said pin 17 is held as the wefthammer makes its forward stroke letcr mines whether the lateral spur 18 of said catch shall be engaged by the shoulder 20 of the weft-hammer and the catch and arm thereby be thrust forwardly to bring about the predetermined change in the operation of the loom. The cooperation of the feelerparts with crank-pin 15 locks the controller in a position which causes it to hold the catch 18 out of the path of shoulder 20 at the time of the said forward stroke of the weft-hammer. A spring 21 applied in connection with rockshaft 14 acts with a tendency to rotate or assist in rotating the said rockshaft in the direction to cause or permit the spur 18 to enter into the path of the shoulder 20.

The new mode of governing the so-called controller or transmitter of the feelcr-devices of a loom through a feeler having a laterally movablefeeler-tip consists in employing in conjunction with the laterally movable feeler-tip a controller-lock or detent which, while the working weft-supply is suliicient to hold the feeler-tip from lateral displacement, locks the controller or transmitter so as to prevent a change in the operation of the loom from being indicated or called, but which, when the extent of depletion of the working Weft-supply becomes such that lateral movement of the feeler-tip takes place, unlocks the controller or transmitter so that the mechanism is permitted to indicate or call the change. In this first illustrated embodiment of features of the invention, the controller-lock 0r detent comprises a lockingmember a upon the rod (1, which locking member coiiperates with the crank-pin 15 of arm 15 of the controller. The locking member a is a raised portion of the rear part of the rod 'a. When the lay is back and the feeler-parts occupy their normal positions shown in Figs. 1, 2, 3, the locking member a is in its idle or inoperative position at the 'rear of the crank-pin 15 and clear of the latter but with its front end closely adjacent thereto. So long as the locking-member a" remains entirely at i will in M the real" be the crank-pin. 15" it will not me vent the controller from. llllilii' in the a. motion to lower the witch 18, when the coin trolley is free otherwise to turn in such (lireotio'n after previously having occiipied a position in which it supports catch le iclozuof the path of the engaging shoulder of the weft-hammer in operation. och time the advancing \veltunnss 3 pushes against the feeling-end 1. of feeler-tip, and, while holding the feeler-tip from lateral dis placement us in Fig. 4-. drives the feelci' parts bodily forward in unison, the forwerri movement carries the locking men ier a lo ward under the elevated crank-pin so :2

look the controller;- thereby with catch 1w elevated. To facilitate the entrance of the locking member a into locking positi n under the cranlopin. 15", the from com 2 of the said locking-member is lOUlMlBi'l oh as shown in Figs. 2 and 3. As the icy recedes from its position in Fig. i. and spring 9 returns the feeler-peits rearward, the THU- ward movement of the feeleoparls (lld'WS the locking member u out of engagement with the crank-pin 15 and returnsit to its idle or inoperative position. i i/hen. however, the forward pressure of e substantially denuded Weft-carrier 4 against feeling-owl 1 of the feeler-tip l deflects the feeleniip laterally outward so that the feeler-tip swings around pivot 7) o fulcrum. on: forces carrier 2 forward while holding" ?.'()(l a rearward. with stop collar 6' in contac t with the front face of lug d, the locking" inemlm a is caused to remain in unlocking po. tion. Hence. the controller remains unlochscl and consequently is permitted to turn so that catch 18 is lowered and engagement tween. catch 18 and the weft-hammer is posmitted to take place, so that the change in the operation of the loom is called.

In the case of the. described construction the locking member a normally occupies its unlocking position at the rear of crank-pin 153, and when the controller is permitted to do so it assumes a position in which the crank-pin 15*" is down in front of said loch-- lI1g-Il16TnllGf and catch 18 is lowered.

During the regular working of the loom the forward movement of carrier 2 that is produced by the push of the contents of the shuttle at every feeling action takes the controller-rest forward out of enga 'ement with crank-pin Thereby the contiollcr is freed so that it may turn unless locked by the ction of the loc mg member a.

In the case the second embodiment of features of the invention, as shown in Figs. 6 to ll, Elli acts to 8, the controller-lock and controller-rest are transferred to and combined with the feeler-tip. That is to say, the 'l'eeler-tip is so constructed and. so combined operatively with the controller that the feeler-tip peforms the functions that in the first embodiment are performed by the separate ci'mtroller-lock and controller-rest. Thus, the tail of the color-tug is furnished with an extension 1 with which thearm. 1 3 of the cmitroller engages. Nor-- mally, the said extension projects under the rear end of the said arm which rests upon the said extension 1 and is supported thereby as in G, and substantially as shown in Fig. 9. Tiei'eby the controller locked with the catch 18 in raised position. Forward mm'emenl; communicated to the elder-parts by pressure of the fillin -mass against the feeling-end oil? the ieeler-tip, carrying them bodily forward in unison without deflection the i eeler-tip, carries the extension i "farther forward under the arm 15 as in Fine. 7 and 9. The return movement of the ieelenparts as the lay recedes restoices the el-itci'ision to its position under re r end of the arm as in Fig. 6. lVhen tl U pressure of a. substantially denuded weft-carrier against the feeling-end l operates o deflect or displace the i eelen as in 11, the turning of-the feelertip around the secondary fulcrum b operates to swing the extension 1 rearward, out from under the end of the arm 15 and 1e leases the said arm, as shown in Figs. 10 and 11. Upon the release of the arm the controller turns until a linger pioiecting i'earwaidly from the top of the arm comes to rest upon the top of the extension 1 as in Figs. 10 and 11. T his turning inovement permits the catch 18 to move into position to be engaged by ine shoulder 10 of the ion wardly nicweft-l miner. to call the in the ope l the loom. In the subsequent rearwa stroke the wefthammer' the resetting cam 92 raises the catch and ZLClsS the contii-oller reversely, thereby raising arm 15 hi ugh to permit extension 1 of the federal p swing in under the arm as the :teelezr-p s recover their normal positions under the action of spring 9 and stop-device of, cl, 6.

The contreller-actuating sprin 21 of the first embodiment may be omitte as in the case of the illustration of the second cmbooiznent. In the absence of the said spring the movement of the controller, when the latte? ijinlocked through the disengagement o'l: extension 1 from arm 15, is due entirely to the action gravity. A spring 21 may be employed in the second embodiment if piiefei'red.

The third embodiment, shown in Figs. 12 to 1G, diliei's from the second embodiment in the replacement of the stop-device a, (Z, e, by a spring-actuated slide 30. The slide 30 acts to hold the 'l'oeler-tip normally in its pres entation-position. It is arranged alongside ca rier 2, and like the latter is mounted in a guideway in the carrier-stand 100, the reduced rod-like extensions 2", of the two parts being passed through holes in the forward. upright portion 101 of the carrierstand, and the actuating springs 9, 90, surrounding the said extensions being confined between said u'gn'ight portion 101" and the front ends oi the body portions of the carrier and slide. A single cross-bar 100 serves to hold the two parts within their guideways. The slide engages by means of a lug or projection 300 upon its rear end with the feeler-tip, and the pressure transmitted to the teeter-tip through this lug or projection operates with a tendency to turn the feeler-tip upon its fulcrum 1 in connection with the carrier so as to hold the fceler-tip against a stop-pin a: upon the carrier. Thereby the feeler-tip is given its presentationposition, and extension 1 of the tail of the i'eelcr-tip kept normally beneath the rear end of arm 15 that it supports such arm and locks the controller from turning to lower the catch 18".

When the forward movement of the lay carries against the feeling-end 1 of; the i'eeler tip a weft-mass suflicient in quantity to prevent lateral displacement of the feelertip from taking place, and the feeler parts in consequence are forced forward without such lateral displacement, the pressure that is tyansmitted through the feelers-tip against the or proiection 300 of slide 30 will cause the slide to go forward in unison with carrier as in Fig. 13. As the lay recedes, spring 90 will carry tne slide 30 rearward in unison with the carrier 2, so that projection 300 by its pressure against the leelen-tip will keep latter pressed against stop-pin w. The action otherwise will be substantially as in the case of the second embodiment. llhen a s1 intially depleted weft-carrier is carried iorwai'd against feeling-end 1 and displaces the feeler-tip laterally as in Fig: 1%, the lug or projection 300 will bea secondary fulcrum for the feeler-tip.
